Narrowing searches based on url, author, date, and other attributes is also possible. For instance, the query [ Streisand sourcename:Techdirt ] restricts searches for "Streisand" to items from the blog "Techdirt".
Examples of other operators follow:

sourceurl:http://www.theverge.com/

items from the blog http://www.theverge.com/

sourcename:"New York"

items from blogs with "New York" in the name

date:10/20/11

items that appeared on 10/20/11

date:[10/1/11 TO 10/20/11]

items appearing between 10/1/11 and 10/20/11

author:"Bill Gates"

items by author "Bill Gates"

title:unsubstantiated

items with "unsubstantiated" in the title

body:"severely polluted"

link:http://www.marco.org/2011/04/16/rumored-apple-hdtv

items linking to http://www.marco.org/2011/04/16/rumored-apple-hdtv

Note: all operators that take urls will accept simple domain names, which match any item at that domain, or complete item urls.
